New Guinea Impatiens plant named ‘Doimtatrure’

ABSTRACT

A new and distinct cultivar of  Impatiens  plant named ‘Doimtatrure’ characterized by its upright, outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely and early flowering habit; relatively large bright red-colored flowers; and good garden performance.

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DOIMTATRURE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of NewGuinea Impatiens plant, botanically known as Impatiens hawkeri andhereinafter referred to by the name ‘Doimtatrure’.

The new Impatiens plant is a product of a planned breeding programconducted by the Inventors in Koka, Ethiopia and Rheinberg, Germany. Theobjective of the breeding program is to create new early and freelyflowering New Guinea Impatiens plants with large attractive flowers andgood garden performance.

The new Impatiens plant originated from a cross-pollination made by theInventors in November, 2012 in Koka, Ethiopia of a proprietary selectionof Impatiens hawkeri identified as code number NN-1161, not patented, asthe female, or seed, parent with a proprietary selection of Impatienshawkeri identified as code number NN10-003550-005, not patented, as themale, or pollen, parent. The new Impatiens plant was discovered andselected by the Inventors as a single flowering plant from within theprogeny of the stated cross-pollination in a controlled greenhouseenvironment in Rheinberg, Germany in April, 2013.

Asexual reproduction of the new Impatiens plant by terminal vegetativecuttings in a controlled greenhouse environment in Rheinberg, Germanysince June, 2013 has shown that the unique features of this newImpatiens plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature, daylight and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Doimtatrure’. These characteristics incombination distinguish ‘Doimtatrure’ as a new and distinct Impatiensplant:

-   -   1. Upright, outwardly spreading and mounding plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching habit.    -   4. Dark green-colored leaves.    -   5. Freely and early flowering habit.    -   6. Relatively large bright red-colored flowers.    -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the femaleparent selection. Plants of the new Impatiens differ primarily fromplants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens flower earlier than plants of the        female parent selection.    -   2. Plants of the new Impatiens have larger flowers than plants        of the female parent selection.

Plants of the new Impatiens can be compared to plants of the male parentselection. Plants of the new Impatiens differ primarily from plants ofthe male parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are not as broadly spreading as        plants of the male parent selection.    -   2. Plants of the new Impatiens have larger flowers than plants        of the male parent selection.

Plants of the new Impatiens can be compared to plants of Impatienshawkeri ‘Tamar Dark Red’, disclosed in U.S. Plant Pat. No. 19,423. Inside-by-side comparisons, plants of the new Impatiens differ primarilyfrom plants of ‘Tamar Dark Red’ in the following characteristics:

-   -   1. Plants of the new Impatiens flower earlier than plants of        ‘Tamar Dark Red’.    -   2. Plants of the new Impatiens have larger flowers than plants        of ‘Tamar Dark Red’.

Plants of the new Impatiens can also be compared to plants of Impatienshawkeri ‘Duemagwis’, disclosed in U.S. Plant Pat. No. 26,782. Inside-by-side comparisons, plants of the new Impatiens differ primarilyfrom plants of ‘Duemagwis’ in the following characteristics:

-   -   1. Leaves of plants of the new Impatiens and ‘Duemagwis’ differ        in lower surface color as lower surfaces of leaves of plants of        ‘Duemagwis’ are red purple in color.    -   2. Plants of the new Impatiens flower earlier than plants of        ‘Duemagwis’.    -   3. Plants of the new Impatiens and ‘Duemagwis’ differ in flower        color as plants of ‘Duemagwis’ have light red- colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the winter in 16.5-cm containersin a polyethylene-covered greenhouse in Encinitas, Calif. and undercultural practices typical of commercial New Guinea Impatiensproduction.
